When St. Tammany Parish Requires a Window Permit

Parish rules generally distinguish between like-for-like replacements and work that affects the structure, egress, life safety, or the building envelope rating.

• Changing the rough opening size or moving a window to a new spot.
• Adding or adjusting a bedroom window to meet egress window requirements for bedrooms in St Tammany Parish.
• Installing impact-resistant windows for hurricane season Mandeville Louisiana or using products rated for high wind zones in Southeast Louisiana, especially where wind-borne debris provisions apply.
